Application filed April 6.

To all i072 am it may concern:

Be it known that I, Josnrn FREDERICK Sauna, a citizen of the United States, residing at Chico, in the county of Butte and State of California, have invented anew and useful Engine-Time Register, of which the following is a specification.

My invention relates to a new and original engine time indicator, which is operated by the compression and vacuum created in a cylinder of an engine to which it is attached, and is composed of a rod or shaft used as an indicator, attached to a plunger which moves past a pressure release port in a cyl inder as pressure is applied and returns as pressure subsides; and the objects of my invention are, first, to save time; second to simplify engine timing, especially for the repairman; third, to overcome guess work without having to tear engine apart.

I attain these objects by the mechanisms illustrated in the accompanying drawings, in which- Fig. 1 is a vertical section of the entire machine; Fig. 2 an external view; Fig. 3 top View; Fig. 4: bottom view; Fig. 5 a group of the internal mechanisms in detail.

Similar numerals refer to similar parts throughout the several views. Hexagon 1, body of cylinder 2, ,1 inch spark plug hole fitting 8, and 2,- inch spark plug hole fitting 4:, constitutet-he outside walls of the mechanism; the combination 3 and 4 may be changed to suit difierent con ditions and objects to which the machine may be attached. t

The pressure, created in the cylinder of the engine during compression stroke by short movements of the piston, enters through passage 5 forcing plunger 6 beyond exhaust port 7 in cylinder 8. Plunger'rod 9 attached to previously mentioned plunger 6, and to indicator-1O goes through and is guided'by plug 11. p i As soon as the piston of the engine stops moving and the pressure subsides, spring 12, guided by plunger stop 13, forces plunger 6 back again beyond exhaust port 7 to its original position. where it rests balanced between spring 12 andspring 14E. Plunger 6 alternates back and forth in the above described manner as often as the piston of engine is moved and stopped, until the said piston arrives at dead center or neutral point between compression stroke and power stroke.

192(). Serial No. 371,660.

At this point plunger 6 remains still, and balanced between spring 12 and spring 14 as above described, thereby automatically indicating the dead center (usually called the upper-dead center on vertical engines) of the compression stroke of the engine, which is the time the ignition is usually set to occur. Immediately as the piston of the engine moves to either side of dead center a vacuum is created which draws plunger 6 towards lower plunger stop and spring guide 15; thus each position of the piston of the engine afifirms the registration caused on the indicator'by the other positions. 7 any pressure or vacuum on back side of plunger 6, when moving back and forth, thus allowing perfect freedom of motion. This mechanism will register every cycle of the piston directly or indirectly. Spark plug hole fittings 3 and 4 maybe changed to suit any other connection or fitting as conditions require.

. As often as vacuum is applied and released plunger 6 moves back and forth in the same manner as when pressure is applied to it and released, but in the opposite direction.

i As the plunger moves back and forth very quickly due to the spring action on both sides of the same, the movement of the plunger will be heard very distinctly, as the plunger makes a noise when. striking the upper and lower stops 13 and 15, and there is a peculiar sound given out when the air rushes out of the ports. v

I claim:
